Patch Changes

• a40b6cd: Experimental broadcast(fn): a live server function whose answer is the same for every viewer. It implies live (and so GET); at the live address every caller with the same arguments shares one server render, and each viewer is a tap on it. A viewer that joins later gets the frame as it stands, then the shared batches; the render ends with its last viewer. The outer body still runs per call (auth, redirects), and the shared render runs under its own request event, so per-viewer state such as the router's query cache never reaches it.

• 9f64ca9: live(fn) now implies GET: a live source is a read by contract, so the declaration grants GET dispatch on the server and connects over the GET transport on the client. live(GET(fn)) keeps working and is equivalent. The client's POST-at-the-live-address path is gone, which trims live pages by ~144 B minified.

• 0222d68: With enableRichArguments(), a server function can take files and blobs anywhere in its arguments. Calls like upload(file, { tags }), upload({ file }) and upload(formData, 1) used to fail before sending. They now send multipart form data, with each file as its own part instead of encoded inside the arguments.

• ee4963a: A live server component's slot record that a commit changes now leaves in the same write as the holes that commit moved, with every arg current. Before, each arg of the occurrence re-sent the record as it updated, so the first copy went out alone with the other args still at their previous values, ahead of the hole. A client fill reading those args could show a state no commit had: the chat's pending message left the outbox before the thread showed its row.

• 5c0d190: renderToStream now reports two failures through the server error hook even when the render has no onError of its own (#4193). A value the serializer cannot handle reaches the render's hook, else the one set with configureServerErrors, as { kind: "render", handling: "serialize" }, and the render settles. Before, it was an unhandled rejection and the render stayed pending forever. With no hook anywhere, the failure goes to console.error. An onCleanup that throws when the render is disposed after a normal completion is now contained as abandon() already did (#4029): it is reported as { kind: "render", handling: "failed" } instead of escaping as an unhandled rejection.

• 6cca8b5: Dev builds now warn with UNCOMMITTED_INPUT_OVERWRITTEN (#4186) when a stateful DOM property binding (value/checked on an input, value on a textarea, value/selected on an option, muted on media) is about to re-write the value it wrote last time over an edit the user never committed to the bound signal — e.g. value={props.name} onChange={commit} with no draft signal, when another dynamic attribute in the same template changes. Runtime behavior is unchanged: the write still happens, once per element and property the warning names the fix (write the signal from onInput, use defaultValue/defaultChecked for an uncontrolled element, or write a rejected edit back with e.currentTarget.value = next).

  Production output is unchanged byte for byte. In dev DOM output both compilers write stateful properties through a new setStatefulProperty(el, name, value) helper instead of the inline el.name = value; hydratable output keeps setProperty, and spread/assign check in the runtime. The check lives only in @solidjs/web's dev build; the production entry carries a plain node[name] = value stub that no production-compiled module imports, so it tree-shakes away.

  The "Form inputs" section of the DOM RFC, the cheatsheet and the solid-2.0 skill now say that a change to any other dynamic attribute in the same template re-runs a stateful binding, link the new code, and drop equals: false as a way to reject input (it is what the warning reports); write the accepted value back with e.currentTarget.value = next instead.
